Description of hot sale Hydraulic digital Dead weight Tester
Pressure Tester in china
KY series Dead weight piston gauge is a high precision and reliable
standard pressure calibrator which is basic on Pascal law and a
statics balance principle. ,we use it on some other gauges to calibrate the daseries DWT is a
high precision and reliable standard pressure calibrator which is
basic on Pascal law and a statics balance principle. It is usually
called piston gauge or manometer, sometimes pressure balance
instrument, major used in the lab and measure workshop, or as a
pressure calibrator.
Measurement range and accuracy of Hydraulic Dead weight Tester :
At ambient temperature(20±2)℃, the temperature fluctuation is not
more than 0.5℃ reference Table 1.
Feature of hot sale Hydraulic digital Dead weight Tester Pressure
Tester in china:
1. Piston and piston cylinder are using high strength, high
hardness, and low temperature expansion coefficient of tungsten
carbide material after, the working environment temperature is
wide, stable performance of 20±5℃.
2. The load center of gravity is low, the weight is directly added
to the piston through the hanging basket, the piston runs smoothly,
the pressure fluctuation is very small, and the value is accurate.
3. Above 25MPa, pressure transmitting medium use diisooctyl
sebacate with small viscosity, to ensure a high sensitivity..
4. The weights of the tester is made of stainless steel.
5. Piston position with displacement sensor monitoring, the piston
up and down stroke is ±1.5mm, the instrument display has the
advantages of sensitive, eye-catching, accurate and so on.
6. Range wide, at the lower limit of 1MPa, the basic error is
±0.02% or ±0.05%, a KY100 type tester, can replace 3 testers of
6,60,100MPa.
7. It is labor saving, and can be easily to add pressure to be
100MPa.
